#6 AVR Plugin problem with OS X
I am trying to install this on my MAC (intel chipset). And i am having a problem with the system not able to recognize the AVR Dragon that I have. I did find that paths it is not able to find the "ATmel part description files system". I have just reinstalled the Crosspack. Is that in there? Am I missing something also?
One last thing, when I turn on the program, I do get the following error:
Description Resource Path Location Type
Error launching external scanner info generator (avr-gcc -E -P -v -dD /Users/danielbock/Eclipse development/.metadata/.plugins/org.eclipse.cdt.make.core/specs.c) Test_1 Unknown C/C++ Problem
Any help would be great. Thanks.
Hi Dan,
the path to the "Atmel part description files" is currently unused by the plugin and therefore not required. (The Atmel Part Description files are part of the Atmel AVR Studio IDE [Only available for Windows] and AFAIK not available separately)
So the problem with recognizing your Dragon must be somewhere else. Maybe you can provide the console output to see where it is failing.
For your second problem: I haven't seen this error message so I don't know where it comes from and what is causing it.
But a few things you could try: check that the file "/Users/danielbock/Eclipse
development/.metadata/.plugins/org.eclipse.cdt.make.core/specs.c" exists and is just a empty file (except for one newline).
Second: execute the whole command ("avr-gcc -E -P -v -dD /Users/.../specs.c") from a shell to check if there is any problem with that.
BTW the "Test_1" in the output. Is that the name of a / the Project?
Thomas
Thanks for the help. However, I still have the same error as before:

Is it the directory error my problem that it says is nonexistent?
+1 on the second problem. I do have the same observation on my MAC installation.
Ok, this seems to be a common Mac problem.
Could someone with the problem ("Error launching external scanner info generator") please open a simple terminal and enter 'avr-gcc'. I am curious if 'avr-gcc' is in the standard system path on a Mac (with the avr-gcc toolchain installed of course)
If it is, then I am out of ideas and for further troubleshooting I would need some OSX user who would be willing to debug the plugin (it is not very difficult, although a little bit of Java expertise would be helpful)
BTW, some googleing for the error message showed that this problem does not seem to be limited to the AVR Plugin but also occurs with other toolchains.
I also have the external scanner problem. If this seems to be a general problem would it still help if I debug the plugin? If yes what should I do?

I'm having the same problem with the warning messages.
I've found one solution, which involves disabling the 'Automate discovery of paths and symbols' option in the default Discovery profile (Debug by default). Of course this only takes care of the warnings themselves, not the actual problem.
Note that the building of source code succeeds, proper hex files are being generated and the uploading via avrdude works. (I'm using an ATXmega128A1 with the AVRIsp mkII programmer).
The only thing that doesn't seem to work correctly is auto-completion for the AVR specific registers and such (I'm assuming this has to do with the warnings).
Weird thing is that when I press 'Open Declaration' on, for example <avr interrupt.h="">, the correct header file is opened... So why isn't this indexed, maybe because the correct environment couldn't be determined?
Running the avr-gcc command in a shell works, and gives the same output when run on a Windows machine with the same setup (same eclipse versions + WinAVR + AVR Studio).
I'm using:
MacOSX 10.6.2 Snow Leopard
Eclipse Galileo - Build id: 20100218-1602 (latest)
AVR Eclipse plugin - Version: 2.3.1.20081204PRD (latest)
CrossPack-AVR-20100115
P.S. The Atmel part description files can easily be copied from an AVR Studio installation, just put them somewhere on your drive (I put them in '/usr/local/CrossPack-AVR') and set a custom path to it within Eclipse... It should be approximately 52MB.
Okay, after some looking around I found the option 'Create Parser Log File'.
When using this option on avr/io.h (this file includes the correct header files for a specific platform) I got the following:
Scanner problems:
#warning encountered with text: "device type not defined" in file: /usr/local/CrossPack-AVR-20100115/avr-4/include/avr/io.h:404
When doing the same with the file I actually need (avr/iox128a1.h) I get:
Scanner problems:
#error encountered with text: "Include <avr io.h=""> instead of this file." in file: /usr/local/CrossPack-AVR-20100115/avr-4/include/avr/iox128a1.h:38
The rest of the files are parsed correctly.
My guess is that during indexation the device type is not set (correctly), which would explain why auto-completion doesn't work.
Sadly, I don't know how to fix this.
P.S. I'm the poster of the previous post, something went wrong with openid.
Hi
I'm using:
MacOSX 10.5.8
Eclipse IDE for C/C++ Developers
Version: Helios Service Release 1
Build id: 20100917-0705
AVR Plug In Version: 2.3.4.20100807PRD
CrossPack-AVR-20100115

avarice: 2.9

gcc-3: 3.4.6
gcc-4: 4.3.3
gdb: 6.8
libusb: 0.1.12
make: 3.81
simulavr: 0.9)
For me, I installed the avr-plug-in (and thanks for making it available!) and the only evidence I see of it is in the about box for Eclipse. Otherwise no sign in project properties (or elsewhere that I can see). I see a few others with this problem online elsewhere.
When I launch a project I get the same error as Mr Bock, except with my path, some of which I replaced with [Path] below, viz
Description Resource Path Location Type
Error launching external scanner info generator (gcc -E -P -v -dD /Users/[Path]/Eclipse/MyMessing/.metadata/.plugins/org.eclipse.cdt.make.core/specs.c) junk-test-plugin Unknown C/C++ Problem
In this case junk-test-plugin is the C project I created.
When I paste the call into my terminal, I it fails for not finding gcc. Adding the prefix "avr-" gives the following result:

The most interesting bit to my (not so very experienced) eye is the following

it's true that the nonexistent directory does not exist.
Anyway, I'm game to debug the Java if you suggest where I should be looking in it.
